The determinants of the Choice between Green and Conventional Buildings in the Gauteng Office market
Full text linkThe purpose of this study is to identify the key factors which drive investment in or occupancy of green buildings by landlords and tenants and to identify the benefits they derive over traditional buildings. In order to assess the significance of certain factors such as rental, hypothesis tests were conducted with logistic regressions and verified by interviews. Three hypothesis were tested two of which looked at the rentals and operational cost for each type of building , these revealed that the medians as well as distributions of each showed no significant differences between the two type buildings. The last hypothesis test various other factors for any significance between the buildings and no significant findings were found. The importance of sustainability is increasingly being emphasized across industries and more so the property industry given their contribution to greenhouse gas emissions. Green buildings were developed to address these consequences. As such it is important to know the financial returns realized in property portfolio to support the case of green buildings in emerging markets
An assessment of the necessity of implementing a blockchain based land registry in South Africa
No full textA research report submitted in fulfillment of the requirements for the Master of Architecture, In the Faculty of Engineering and the Built Environment , School of Construction Economics and Management, University of the Witwatersrand, Johannesburg, 2024Background statement: Several nations have recently implemented blockchain-based land management systems, focusing on land registration, titling, recordation, and information management, to enhance transparency, trust, data security, data quality, and immutability through consensus mechanisms. This technology streamlines access and tracking of land records, reducing fraud, corruption, record manipulation, and property resale while lowering transaction costs. These advantages aim to address issues of inefficient and untrustworthy land records in less developed countries. Problem: South Africa faces challenges, ranking 108 out of 190 in property registration according to the World Bank, with lengthy procedures (7), extended transaction times (23 days), and high costs (8% of property value). In contrast, blockchain-adopting countries like Sweden and Georgia are ranked at 9 and 5, respectively. Despite these inefficiencies blockchain technology has not yet made an inroad into the land registration or transaction process. Aim – The aim of this study is to investigate the potential use of blockchain technology to digitize land registration in South Africa. Methods: This paper investigates a blockchain property registry pilot project in Khayelitsha, South Africa, using Peled's theoretical framework and employs qualitative research methodologies, including case study analysis and expert interviews, supplemented by a systematic literature review. Outcomes: The study reveals significant challenges in South Africa's land registration, including unreliable land records, informal land tenure systems, limited access for marginalized communities, corruption, weak legal frameworks, post-colonial property rights legacy, and inefficient real estate transactions. Despite the promise of blockchain, these issues persist, hindering progress. Eight key factors obstruct blockchain adoption in South Africa's land registry, including legal barriers, organizational resistance, technological hurdles, resource constraints, political and social factors, and trust-related issues. The case study identifies additional obstacles, such as misalignment of interests, lack of formal agreements, data quality issues, and further legal barriers. Nonetheless, the pilot project managed to create a "pseudo title deed" with potential benefits for the city. This study suggests the application of blockchain in state-subsidized housing developments to enhance data security and enable electronic land transactions. It emphasizes the need for a combination of expertise, infrastructure readiness, and procedural changes to facilitate innovation in the public sector. Despite the potential, the study concludes that South Africa's land registry is not yet prepared for widespread blockchain implementation, citing legal, technological, and organizational challenges. Significance: This research is the first to explore the limited adoption of blockchain technology for land registration in South Africa, contributing valuable insights to the field. This paper identifies critical factors for successful blockchain-based property registry implementation, offering insights for legislation, policy development, and land registration system design to address inequalities and improve land tenure in developing countries. It outlines a potential path for South Africa's Deeds Registry to implement blockchain technology in state-subsidized housing developmentsMM202

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
